A 22-year-old man was sentenced to life in prison, with the possibility of parole, after pleading guilty to felony murder Tuesday in the 2007 stabbing death of his 16-year-old girlfriend, according to Clayton County District Attorney Tracy Graham Lawson.

Xavier Alexander Parks, who was listed in court documents as homeless, pleaded guilty to killing Antoinette McDonald, according to Lawson.

The two argued after McDonald told Parks she wanted to end their relationship the day of the incident, Aug. 10, 2007, according to the application for an arrest warrant Clayton County Police sought in the case.

The incident occurred at 1349 Grovener Way, in Riverdale, according to court records.

"Parks had just been released from the Clayton County Jail two days prior to the incident for a violation of probation on domestic charges related to McDonald ... and was at the incident location to pick up their one-year-old daughter," police said in the warrant application.

According to two witnesses, a verbal altercation became physical, and Parks stabbed McDonald "numerous times on and about the neck with a knife," the application states.

Parks pleaded guilty to the felony murder charge before Judge Albert Collier Tuesday, according to Lawson, who represented the state in the case.
